MACHINE FOR BENDING TIN-ROOFING CLEATS.

SPECIFICATION forming part of Letters Patent No. 312,013, dated February10, 1885.

Application filed November 17, 1884. (No model.)

To all whom it may concern:

Be it known that I, STANLEY A. PniLLIrs, a citizen of the United States,residing at Amherst, in the county of Hampshire and State ofMassachusetts, have invented new and useful Improvements in Machines forBending Tin- Roofing Cleats, of which the following is a specification.

This invention relates to improvements in machines for bendingtin-roofing cleats, and is in the nature of an improvement upon mypatent of September 30, 1884, No. 305,757, the object being to improvethe bending-bar and its abutment-block to adapt them to a greater variety of work, and to improve the mechanism for operating said bar; toprovide an improved knocking-out slide and means for operating thelatter. I

In the drawings forming part of this specification, Figure 1 is aperspective view of a machine for bending rooting-cleats embodying myimprovements. Fig. 2 is a side elevation, partly in section. Fig. 3 is aview of the bed and turning-bar of the machine, showing the knocking-outslide thereon, some of the upper parts of the machine being removed.Figs. 4 and 5 are Views of detail parts, and Figs. 6 and 7. show thedifferent forms of cleats bent by the machine.

In the drawings, A is a table or bench on which the machine is securedin a position to be operated, and of which D is the bed.

F is the turning-bar, hinged to the front end of the bed D, having nearone end a flat surface, a, and near the opposite end a combined flat andinclined surface, respectively numbered 4 and 5.

Attached to one end of the turningbar F is a grooved pulley, m, and agrooved segment, i, of a pulley is attached to said bar between the endthereof and the pulley m. The bed D,

directly back of the bar F, is grooved to receive the arms 12 of theknocking-out slide, as shown in Fig. 3. A piece, 15, on which is thestandard E and the inclined face 2, is secured to the bed just back ofsaid grooved portion thereof. Said piece having the standard E thereon,is shown in bottom View in Fig. 4.

V A plate, I), is secured on the said grooved part of bed D, coveringthe arms 12 of the slide 10, thereby forming operating passages for saidarms, and the front edge of plate I) (see Fig. 2)

The rear end of the slide 10 is turned upward behind the piece 15, asshown in Fig. 1. A chain, a, one end of which is attached to a treadle,w, passes partly around wheel at from its rear side, and is secured at apoint on the periphery of said wheel by a pin, 0, and from the latterthe chain continues, and its-end a is attached to the end of a spring,1;, which is secured under thebed D. A hammer, 9, adapted to strikeagainst the rear end of slide 10, is

secured on a shaft, 8, which has a reciprocating rotary motion insuitable bearings in the stand ard E, and said shaft has an arm, a,fixed on its outer end. A coil-spring, 'I on shaft 8 has one endattached to the latter, and the other end to standard E, as shown inFig. 1. A lever, e, is pivoted centrally on the side of the standard h,and to its lower end is attached the rod f, having a hook, 6, on itsfree end, which is adapted to rest on the grooved edge of segment 2',and to engage with the latter at the front end of its groove, and beknocked out of engagement by the opposite end of the segment-edge whenthe latter swings up and strikes said rod back of thehook. The upper endof lever e is connected with the end of arm 0 on shaft 8 by the rod (1.Thus when segment i engages with hook 6, as aforesaid, lever e swingsand draws up the hammer 9 against the resistance of spring y,'and whensaid hook is knocked off from the segment, spring y acts to swing shaft8 and drive the hammer 9 against the slide 10 with suflicient force todrive it forward, causing the ends of arms 12 thereon to strike the endof a cleat between plate b and the bed and knock it clear from themachine.

In operating my machine to bend cleats of the form shown in Fig. 7,numbered 11, a piece of tin-plate of rectangular form has its end forcedunder plate I) opposite the flat surface a on bar F. Treadle w is thenoperated, turningwheel m, segment z, and the bar, bringing the latterover so that face a lies on the top of plate b, the tin-plate beingthereby bent over the edge of plate I), as shown in Fig. 2, and the partbetween said bent portion and its opposite endbeing bent at rightangles, as shown by the cleat 14, between the bar F, plate I), and thefront side of standard E. When the treadle is released, spring 12 rollsbar F back to its starting position, as in Fig. 1, and said movement isfollowed by theblow of the hammer 9 against slide 10, as abovedescribed, whereby thebent cleat is knocked off from the machine.

To bend a cleat, 13, such as is shown in Fig. 6-that is, one in whichits main portion is not bent at right angles, but at aninclinethe pieceof tin which is to form the cleat is placed on the machine, as beforestated, but between the inclined faces 2 and 3, so that when the bar Fis turned over the piece will be clamped and bent between the faces 2,5, 4, and 3,whereby it isgiven the requisite form. The bent cleat isknocked out, as before stated.

For forming cleats of both of said forms, the piece 15 forms theabutment against which the. free end of the tin strip is forced by thefolding-bar F.

By feeding cleat-strips to both ends of bar F, both forms of cleats 13and 14 can be bent at the same time.

What I claim as my invention is- 1. In a machine for bendingmetallic-roofing cleats, the combination of the folding-bar F, havingthe faces 4 and 3, the plate I), the abutment 15, having the inclinedface 2, the slide 10, and means, substantially as described, for givingthe folding-bar a reciprocating rotary motion, and for driving the slidetoward the folding-bar after the cleat has been bent, substantially asset forth.

2. In combination, the folding-bar having its face part a at rightangles to the front edge of the bar, the face 4, in a plane with theface a, and the face 3,at an inclineto the face 4, the plate I), theabutment 15, having aportion of its side adjoining said plate at rightangles thereto, and a portion thereof, as face 2, at an incline to theplate, the slide 10, having arms 12, and means, substantially asdescribed, for giving the folding-bar a reciprocating rotary motion,-andfor driving the slide toward the folding-bar after the cleat is bent,substantially as set forth.

3. In combination with the cleatfolding mechanism, substantially asdescribed, the slide 10, having arms 12 12 thereon, the hammer 9, andmechanism, substantially as described, operated by the movements of thefolding mechanism for causing the hammer to strike the slide,substantially as set forth.

4. In combination,lever e, rods d and f, the latter provided with hook6, segmentt', shaft 8, having thereon arm 0, and the hammer 9, thespring y, slide 10, and means, substantially as described, forreciprocally rotating said segment, substantially as set forth.

5. In combination,wheel m, segment 1', chain a, secured at a point onsaid wheel the treadle w, spring 1), rod f, having hook 6 thereon,slide10, the hammer 9, shaft 8, arm 0, spring y, rod d, and lever e,substantially as set forth.
